Urine is transported to the bladder:
a. from the medulla of the kidney to the renal cortex.
b. by peristaltic contractions of the ureters.
c. only after relaxation of the internal sphincter.
d. by contraction of the renal capsule.

The correct option is: b.  by peristaltic contractions of the ureters.

Explanation:

Ureters are the long tubes that connects each kidney to the urinary bladder.

The urine is passed into the ureters from the kidneys and then the muscles present in the walls of the ureters contract and pass the urine into the bladder. This process is called peristalsis.

Therefore, the urine is transported to the bladder by the peristaltic contractions of the ureters.
